RE: 'AI' CANNOT become conscious, nor even (self)aware - 'it' even 'knows' that itself

I have a different opinion about it.
To let ChatGPT explain what consciousness is and use this then as an argument against AI ever achieving consciousness, is ... not very smart, sorry.

You can´t rule the possibility of a self reflective AI with what we know today (which is not much) unless you introduce religion.

Maybe you are right and there will never be a self reflective AI, or you are wrong, and there will. But better be prepared about it and try to make the best out of it.
It is like "will there aliens visit Earth". Maybe yes, maybe not, but don´t exclude the possibility, and prepare for a way of cooperation.
